Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive and moisture-sensitive nature, this product must be stored under an inert atmosphere (argon or nitrogen) at recommended temperatures, typically between 2°C and 8°C for extended stability. The container must be kept tightly sealed in a cool, dry, and well-ventilated area, away from sources of ignition, moisture, and incompatible materials such as acids, oxidizers, and protic solvents.
